Good find Scotty - Never have heard about the little jet engines on the end of the rotor blades before. Now wonder what happened to that design................

Don't know Dex but here is another one just for you grass growers.

Try this one, Dex:

An awesome design, such an achievement generations ago. Perhaps the earsplitting noise was a slight issue...

Interesting, I wonder why the design never took off.

Amazing - thanks for that find too Lyle. Hard to believe someone hasn't picked up on that technology since. Was there other drawbacks other than noise I wonder. Interesting reading about the scale back led by government in Britain on Helicopter companies. I know I'm forever a cynic but I wonder what was really going on behind closed doors.

Here is the Wikipedia article on tipjets, with links to a number of designs. One, the French Sud Ouest Djinn had 178 examples built.

Why was the Rotodyne dropped, and almost all evidence of it obliterated? There have been (and continue to be) plenty of amazingly stupid decisions by governments. Then there are the conspiracy theories.

 

It's very instructive what we learn long after the event; NATO chose the Lockheed F104 Starfighter over a promising British jet fighter. Much later the Lockheed bribery scandal made the headlines.

Located another tip-jet helicopter not previously listed (not even in Wikipedia) in the Ed Coates Collection. It's called the SNCASO 20SO1110 Ariel:

Another unusual concept - triple rotors (note the Comet in the background at Farnborough):
